I agree, you could give more information... however, consider an approach like this:

In your puzzle class, you may have a Value[][] member for storing the values. You could do something like this

public Value get(int x, int y) {
    return values[x][y];
}

public void set(int x, int y, Value v) {
    values[x][y] = v;
}
